So I have just discovered dynamic hair and have been having a marvelous time adding hair to everything - a dog, a cat... a car... eyeballs. Anyhow you get the idea.

But the issue I am having is that when I go back to the assembly room and try to pose anything, the pc goes into a series of calculating hair exercises everytime I try and do anything. It is making posing very slow indeed, as when anything moves, even a tiny bit, I have to wait 4 or 5 seconds while it does it's recalculation dance.

Is there any way to disable this in the assembly room? How can I calculate the hair only once when I am ready to render?

Any help would be appreciated.

 The fastest way to deal with that issue is to simply relocate the Hair Object away from the model in the Properties Tray. Then you can pose to your hearts content.

When done posing, simply drag the hair object back to the correct location in the Properties Tray and your hair will be ready to go.

...Yeah, that should work fine. Awesome.

That has really helped me out. Working my way through your tutorial series at the moment as well Mark, and they are great as well.

Thanks for all of your help...

Now what can I put hair on next?

Trees maybe, those trees could use some hair... but then again, what can't?

 Glad the tutorials are helping out!

You can also  set your hair count to zero and then re-up it when you finish posing, it won't calculate then either. If you forget , the esc key stops the calculating.

I haven't worked with hair yet, but if you turned off the visibility would that stop the calculations?  I tried a quick ball but just moving doesn't seem to cause calculations :D so I couldn't figure out how to test it (yet)

Oooo Nice tips! Thanks!
